  • Patent number: 10500884
    Abstract: A thermal sensitive media for use with labeling or identification methods is disclosed. The thermal sensitive media comprises a media layer and a thermally sensitive record layer formed upon at least one surface of the media layer. The thermally sensitive record layer forms a visually discernable colored image in response to heat. However, the colored image is subject to degradation as a result of exposure to ultraviolet radiation within a known photodegradative wavelength range. An ultraviolet protective coating layer may then disposed over the thermally sensitive record layer. A lamination layer is positioned internal to the media layer and comprises a matrix of micro heating elements driven by radio frequency (RF) power. The matrix of micro heating elements are arranged in a pin array to energize the micro heating elements within the laminated media structure to create a simple numeric image.

  • Publication number: 20130231242
    Abstract: Dye and developer components of a leuco dye system are separately microencapsulated. The microcapsule walls are fragile to the point of being easily ruptured. The microcapsules are mixed combined into a coating composition that is applied to a substrate and dried. Forces applied to the substrate, such as by the application of fingers or a writing instrument, rupture the capsule to produce a color change by interaction of the leuco dye system components that are released upon rupture of the capsules.

  • Patent number: 8513160
    Abstract: The present invention provides a heat-sensitive recording material that has high gloss and excellent absorption and scratch off properties against sebum soiling; and a method for producing the heat-sensitive recording material. More specifically, the present invention provides a heat-sensitive recording material containing a heat-sensitive recording layer, an intermediate layer, and a protective layer, which are sequentially formed in this order on a support. The heat-sensitive recording layer contains a leuco dye and a developer; the intermediate layer contains an aqueous adhesive; and the protective layer is cured by irradiation of an ultraviolet- or electron-beam-curable resin composition with ultraviolet light or an electron beam. The heat-sensitive recording material additionally contains, on the protective layer, an uppermost layer which contains an aqueous adhesive and a pigment having a mean particle diameter of not more than 100 nm.

  • Publication number: 20130123101
    Abstract: A heat-sensitive recording material includes at least a paper substrate, a heat-sensitive recording layer arranged on the front side of the substrate and which has at least one dye precursor and at least one color acceptor, wherein dye precursor and color acceptor react with one another under the action of heat to form color, and an authenticating security feature. The authenticating security feature is a mark which is applied to the back side of the paper substrate and which is made of a tincture having at least one organic solvent. A barrier coating is arranged between the substrate and heat-sensitive recording layer and is suitable to protect the heat-sensitive recording layer against penetration of the tincture into the heat-sensitive recording layer from the back side.

  • Patent number: 8440588
    Abstract: A dye resin ink application process using flexographic printing, flood coating, tinting, or other suitable technique or process to add a color layer on top of a thermal ink layer of a material. The color layer provides a background color, such that upon application of the heat source, the thermal image appears as being imaged onto the background color. The process can be used to make heat-sensitive direct thermal labels or thermal paper rolls, including cash register-type rolls, poster printer format rolls, etc. The process permits thermal-inked material to be produced in various colors in relatively small print runs using conventional equipment.
